Timing Chain Choice

I'm putting 302 heads and XE268 Comp Cam on my 318 with stock bottom end. It has an Edelbrock Performer intake with 750 Holley and headers. What I need to know is a good timing chain and gear to put in while its all apart. I've heard that a Cloyes double roller is a good choice, but when I check them out there are several to choose from. Can anyone give me a part number or some advise on which would be the right choice for my setup? Car is a street car and maybe a rare trip to drags. I appreciate any opinions. Mike :scratch:
